Milltek Sport Secondary Catalyst Bypass Pipes for BMW M4 F82 F83 and M4 Competition 2014 to 2018 - Non-OPF - Part No. SSXBM1032
Unlock the true sound and performance potential of your BMW M4 with the Milltek Sport Secondary Catalyst Bypass, part number SSXBM1032. Designed for the BMW M4 F82 Coupe, F83 Convertible and M4 Competition models from 2014 to 2018, these secondary cat bypass pipes are engineered for Non-OPF cars and must be used with a Milltek Sport cat back exhaust, alongside either Milltek Sport or OE primary downpipes. This is the ultimate secondary decat upgrade for drivers who want sharper throttle response, faster turbo spool and a deeper, more aggressive S55 exhaust note.
Every Milltek system is designed, developed and hand finished in the UK by time-served craftsmen. Produced from aerospace grade type 304, non-magnetic stainless steel, these bypass pipes offer exceptional durability, corrosion resistance and long-term performance. Precision mandrel bending ensures constant-radius pipework for optimised gas flow, while enlarged bore diameters over stock help free up power without sacrificing mid-range torque. Milltek’s renowned acoustic development delivers a sporty, crisp tone without intrusive drone or cabin resonance when paired with a Milltek Sport cat back.
